OLYMPIC swimmer Eamon Sullivan is expected to face court over a joyride on a pensioner's scooter that led to a police report of assault.

Sullivan, 27, from Western Australia, was in Adelaide for a buck's party on October 18 for an AFL footballer and was drinking at the Prince Albert Hotel in Gawler when it's alleged he borrowed a motorised scooter, often called a gopher, belonging to pensioner John Guppy.

Mr Guppy told the Nine Network that one of the men at the buck's party asked "for a spin" on the scooter.

Nine said Sullivan and a footballer took it on to the footpath and crashed into a table outside the pub, injuring two people.

Police have confirmed that a 27-year-old man from Western Australia was reported for disorderly behaviour and two counts of assault.

Sullivan's management has acknowledged there was an incident, but says no charges have been laid.

"Eamon was in Gawler for a friend's wedding. Whilst it is apparent that an accident occurred there is no evidence that Eamon was the party responsible for any such accident.

"We are able to confirm that there are no police charges which have resulted from this accident."
